1) 2/8 +5/12 = 1/4 + 5/12 = 3/12+ 5/12 = 8/12 = 2/3
2) 4/3 + 2/5 = 20/15+ 5/15 = 26/15 = 1 11/15
3) 10/12 + 1/4 = 5/6 + 1/4 = 20/24 + 6/24 = 26/24 = 1 2/24 = 1 1/2
4) 3/5 + 3/2 = 6/10 + 15/10 = 21/10 = 2 1/10
Odpowiedź:
2/8 + 5/12 = 6/24 + 10/24 = 16/24 = 2/3
1/4 + 5/12 = 3/12 + 5/12 = 8/12 = 2/3
4/3 + 2/5 = 1 1/3 + 2/5 = 1 5/15 + 6/15 = 1 11/15
10/12 + 1/4 = 10/12 + 3/12 = 13/12 = 1 1/12
3/5 + 3/2 = 6/10 + 1 1/2 = 6/10 + 1 5/10 = 1 11/10 = 2 1/10
